IMPROVEMENT IN CULTIVATQRS.

Specification forming part of Letters Patent No. 151,733, dated June 9, 1874; application filed February 21, 1874.

To all 'whom t may concer-n Be it known that I, WILLIAM M. WATSON, of Tonica, in the county of La Salle and State of Illinois, have invented a new and valuable l mprovement in Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

- Figure l of' the drawings is a representation of a plan view of my cultivator. Fig. 2 is a sectional view of the same. Figs. 3, 4, 5, and 6 are detail views of the same.

This invention has relation to cultivators which run astride of the rows of plants; and it consists in a novel neck-yoke attachment, which is so applied that it will keep the cultivators upright; at the same time it will allow vertical and lateral vibration, and also a longitudinal sliding movement of the beams independently of each other.

The object of this invention is to provide an efficient cultivator of the character mentioned, which can be used without axle, wheels, and their connections, and thereby to avoid the expense attending their construction.

In the annexed drawings, Sheet l, A A designate two cultivator-beams, to each one of which two shovel-standards, B B', are secured by means of transverse bolts; and between each one ot' these standards and its beam a block, a, is applied, the thickness of which determines the distance between the shovels b b on the standards B B. The rear outside shovel-standard of each beam A has a handle or stilt, C, suitably secured to it, by which the plowman guides the shovels along the rows.v D D are the draft-tongues, which are secured to the inner sides of the beams A A by means of long bolts, on which clamping-nuts are applied. Between the ends of the beams and draft-tongues thus connected I introduce wedges c, by means of which the tongues can be set at an angle with respect to the beams, and the line of draft regulated and adjusted, as may b e required. Wedges of dierent degrees of taper may be used, and they may be applied in front of the connecting-bolts, as shown in Fig. l, or they may be applied in rear of these bolts. If the wedges c are not used, and the beams and tongues are bolted together, as shown in Fig. 3, the line of draft will correspond with the straight beams A A, and the shovels will run straight. The advantages of this construction are, simplicity in the adjustment of the tongues, and a saving of lumber in consequence of my being able to use short pieces. G designates a neck-yoke for the animals which draw the machine, and J J are the sin gle-trees. The neckyoke Gr is attached to the tongues D D at or near their front ends, and the single-trees J J are pivoted to blocks e e, which are secured to the front ends of the cultivator-beams by one or more of the bolts which areused to unite these beams to the draft-tongues. The neckyoke is connected to the tongues D D by means of long staples h and g, which allow endwise movements of each tongue and its cultivatorbeam independent of the other tongue and beam, and at the same time keep the shovelstandards upright. By thus attaching the tongue to a neck-yoke each horse draws his own load and no more.

Fig. 4, Sheet 2, shows a modication of the neck-yoke attachment, which may be used it' there be any difficulty in keeping the cultivatorstandards upright. G designates this neck-yoke; jj, stay-straps; and lok, martingales, which are attached to the neck-yoke. The hame-straps pass through the eyes in the staystraps, and the bellyband or girths pass through the eyes in the martingales. This will keep the ends of the neck-yoke down to their place, and prevent the cultivators from tipping over. The holes i i through the neckyoke G are for the staples k of the tongues to play through.

Figs. 5 and 6 show the neck-yoke loosely attached to the draittongues by means of vertical bolts and long staples.

For the purpose of preventing the plows running too close together, I secure a checkarm, N, to the inner side of one of the beams,

or to the inner side of one of the draft-tongues, the length of which arm limits the approach of the shovels toward each other. When the corn which is under cultivation is large enough the rear ends of the cultivator-beams are con- Vnected together by means of an arched bar,

PATENT OFFICE.

2. The combination, in a straddle-row cultivator, with the independent sliding plor draft-tongues, of a neck-yoke connected to said tongues, and arranged to prevent lateral rocking of the same, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my naine in the presence of tivo Witnesses.
